A Glenrock man was killed when he lost control of his vehicle on Cold Springs Road west of Douglas Tuesday evening.

According to the Wyoming Highway Patrol, 49-yr-old, David L. Geho, was westbound on Highway 91 when he drifted over the centerline.

"The driver then over-corrected the vehicle steering to the right and then again to the left, which caused his vehicle to go into a broadside slide and then off the roadway on the left side going down a steep embankment."

Highway Patrol Sgt., Steven Townsend says the GMC Envoy rolled two times. Townsend says Geho was not wearing a seat belt and was ejected during the rollover.

He says, investigators are determining if alcohol contributed to the crash.
